Abstract

There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit (60), a holder (35), a movable shaft (43), a movable yoke (48), a movable contact piece (49) having movable contacts (49a) at both ends, fixed contacts (33a), and a fixed yoke (51). At the time of excitation of the electromagnetic unit (60), the movable shaft (43) moves to the holder (35) side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke (51) and the movable yoke (48) due to a magnetic field generated by a current that flows into the movable contact piece (49a) as a result of the movable contacts (49) coming into contact with the fixed contacts (33a). The movable yoke (48) is then attracted to the fixed yoke (51).
